feature request: document kingsuper bridge node snapshot

[jcstein]

https://kingsuper.org/snapshots/celestia-bridge-mainnet - note that it is a community snapshot, and not archival

also add kingsuper to consensus nodes if it's not already there, at least a link to the site

Ideally, we need more than one proposer of the snapshots to call it a day and close with docs being done
